LalBrew Windsor™ – British-Style Beer Yeast

LalBrew Windsor™ is a true English ale strain that produces a balanced fruity aroma with lower attenuation due to an inability to metabolize maltotriose. LalBrew Windsor™ is one of the original Heritage Strains selected from the Lallemand Yeast Culture Collection when Lallemand Brewing was founded in 1992. Beers created with LalBrew Windsor™ are usually described as full-bodied, fruity English ales. LalBrew Windsor™ is a consistent and robust strain that produces moderate levels of alcohol and the balanced flavor and aroma characteristics of the best traditional English ales. Traditional styles brewed with this yeast include but are not limited to Milds, Bitters, Irish Reds, English Brown ales, Porters and Sweet Stouts.

Classified as a Saccharomyces cerevisiae, a top fermenting yeast.
Typical Analysis of LalBrew Windsor Yeast:
Percent solids  93% – 97%
Living Yeast Cells  ≥ 5 x 109 per gram of dry yeast
Wild Yeast  < 1 per 106 yeast cells

Diastaticus Negative
Bacteria  < 1 per 106 yeast cells
Finished product is released to the market only after passing a rigorous series of tests
*According to the ASBC and EBC methods of analysis

In Lallemand’s Standard Conditions Wort at 20°C (68°F) LalBrew Windsor yeast exhibits:
Vigorous fermentation that can be completed in 3 days
Medium attenuation and Low flocculation
Fruity and Estery flavor and aroma, typical of traditional English style ales
The optimal temperature range for LalBrew Windsor yeast when producing traditional styles is 15 – 25°C (59 – 77°F)

Windsor does not utilize the sugar maltotriose (a molecule composed of 3 glucose units).
Maltotriose is present in wort in an average 10-15% of all malt worts. The result will be fuller body and residual sweetness in beer. Be advised to adjust mash temperatures according to desired result.
Fermentation rate, fermentation time and degree of attenuation are dependent on inoculation density, yeast handling, fermentation temperature and nutritional quality ofthe wort.
